The bar 49, end-members 42 and blocks 43 are xedly secured together by screws 45. The end-members 42 at the front end of each unit are supported on the hubs of the sprockets 38, and the end-members 42 at the rear end of each unit are supported on the hubs of the 1 sprockets 39. Each bar 49 is provided on its upper face with tracks 4| for individually guiding the rollers of the chains 31 of one or" said groups. The sprockets 3S for each unit are confined between and support the end-members 42 at one end of bar 49, and the sprockets 39 are conned between and support the end-members 42 at the opposite end of the unit. Plates 4'! are xedly secured to some of the channel bars 49 (Fig. 5) and are extended to underlap the bars 40 of adjacent units for closing the gaps between adjacent bars.

A side wall 43 (Figs. 1 and Ll) is provided at one side of the delivery section and is pivotally supported at i9 on the side-beam 3d (Fig. 4) so that it may be folded downwardly for convenient access to the filling-material being conveyed by the delivery section. At the opposite side, a wall 5|) is provided which is removably supported for placement between the units of the delivery section which are transversely adjustable for different spacing, as hereinafter described.

A series of upper conveyor units and a series ci lower conveyor units form continuous compressor and spout sections for successively compressing the filling-material and conveying it, while compressed, intc a casing. rI'he upper series of units is vertically adjustable for filling casings of different thicknesses. 'Ihe transverse spacing between the co-acting units of the upper and lower series is variable for filling casings of diiferent widths.

. Each of the compressor and spout units includes an inclined portion for compressing the filling-material and a straight portion for conveying the compressed material into the casing, a group of endless conveyor chains which extend continuously along the inclined and straight portions of the units, and a supporting structure for each unit which includes a guide bar and a group of sprockets for driving the chains. By utilizing chains which extend continuously in the compressor and spout portions of the units and a single guide structure for each unit, the construction is greatly simplified.

Each upper and lower conveyor unit of the compressor and spout sections comprises: a group of three endless chains 59 which extend around sprockets 62, the hubs of which fit a. drive shaft which is angular` in cross-section; a channel bar generally designated 89 which functions as a guide for said group of chains, and includes an inclined portion 6| and a horizontal portion 53; a pair of side members or plates 'i9 which are carried on shoulder ends S8 (Fig. 22) of the hubs of sprockets B2, and are secured together in fixedly spaced relation by a sleeve "i4, and a screw or rod extending in the sleeve; a shoe 88 which is xed around the outer end of the cross-member of channel bar 8d, around which the chains travel; and a guide shoe 99 which is xed on one face of the channel bar 89, along which the idleA reach of the chains travel for guiding them at the bend between the angular and horizontal` portions of said chains. Each chain G9 includes side links 82 and rollers 33. The face of guide bar 80 along which travel the reaches of the chains which engage the filling-material, is provided with longitudinal tracks 84, on which rollers 83 travel and grooves 85 for the side links 82, for individually guiding the chains in parallel paths. The idle or return reaches vof chains'f travel between the side flanges of bar 80 and guide shoe 9D which is xedly secured by screws S2 to bar 8U-, is provided with tracks 94 for the rollers 83 and grooves 96 for the side links 82 for individually guiding the chains 59 of the unit. The shoe is bevelled as at |09.

The side nanges of each channel bar 89 are eX- tended forwardly of the front end of the chains 69, and a cross-pin |30 (Fig. 8) is fixed therein and extends through lugs |3i, which are fixed to shoe 88 between the chains. This cross-pin effectively strips the filling-material, such as cotton, from the front ends of the chains.

The sprockets 62 for the lower series of compressor and spout units are mounted on a transverse shaft H4 which is journalled in the side frames 39, and the sprockets 62 of the upper series of units are mounted on a transverse drive shaft ||5 which is supported for vertical adjustment with the upper series of units. The lower series of the compressor and spout units are supported by a pair of cross-bars |94, |05, which are spaced apart by blocks |8 and are iixedly secured in seats I9 formed on side frames 39. The upper series of compressor and spout units are supported by a pair of cross-bars ||2 and ||3 which are spaced apart by blocks H1, and are xedly secured to a frame |32 which is vertically adjustable, as hereinafter described. Blocks ||8 and a bar lita fit between the cross-bars |04, |05, and similar blocks fit between the crossbars I I2, |3, to which the units are connected as hereinafter described.

In practice it is advantageous to keep the chains taut for effectively feeding the filling-material and for preventing it from packing between the guide bars and the conveyor chains. The invention provides means for expeditiously tightening the chains when they become loose from stretch or work.

Each guide bar 80 is slidably connected to its associated pair of side members 19 by a block |28 which is xedly secured to said bar, and provided with a horizontal slot |29 through which the spacer sleeves 14 extend. Said slot |29 is horizontal to permit horizontal sliding movement of the guide bar to and from the sprockets E2 for tightening the chains 50. Each guide shoe 9.0 is xedly secured by screws 92 to channel bar 80 and is slidably supported so that forward movement or adjustment of the guide bar 38 will tighten the chains 60 carried thereby during this sliding movement and the horizontal relationship of the spout portion of the chain will be maintained.

The lower face of each shoe 90 of the lower series of units slidably ts the top face of stationary supporting bars |94 and |95. The upper face of the shoes 99 of the upper series of units slidably lits the lower face of supporting bars H2 and H3. Each shoe 99 is connected below a block ||8 or a bar ||8a which fits in the space between one pair of stationary cross-bars |94, |05 or l I2 and H3, and is adapted to be clamped to said block |8 or bar |8a by a screw i i9 which is threaded to said shoe. Each block 8 and the bar ||8a is confined vertically in the spaces between the supporting cross-bars by a plate |20 and the shoe 9S. Each screw I9 extends through a slot |25 in its associated block |8 or bar |8a,

and' is provided' with 'ai shoulder lwhich-'is adapted Each shoe 190land-the 'guide-barl'xed thereto, iwhen itsf connected :screw |19 is-released, is

A longitudinal bar |89 is provided for each of the upper units and the lower compressor and spout units, and has its front end fixedly secured to one of the bars |8| on the group of units a. A brace bar 206 extends diagonally between the outer end of bar |8| and the plate |20 which is xed to the inner end of bar |l8a of each of said upper and lower units. The bars |89 and 206 constitute a rigid connection between the bars H8 and |8| to which the shoes 90 of units of group a are connected.

The linkages for varying the transverse spacing of, and the bars |89 and 2|8 for, the lower compressor and spout units are identical in construction with those illustrated with the upper units, and, therefore, the linkage for the lower unit has not been illustrated in detail.

When the compressor and spout units are spread apart for filling the maximum width of casing for which the machine is designed, the units will be in relative position, as illustrated in Fig. 21. When a narrower casing is to be filled, the series of units a will be shifted inwardly and the linkages will gradually close the spaces between the intermediate unit c, the inner unit a, and the fixed unit b. This permits the units to be transversely adjusted for close variation within a predetermined range. For a greater range of variation, the invention provides for a side closure or partition which is applicable to any of the units of the group a, as hereinafter described.

The transverse spacing of the upper and lower units is conjointly variable by connections between them which produce conjoint shifting of the upper and lower groups of units a and the linkages operable thereby. These connections are adapted to be maintained in all vertical adjustments of the upper series of compressor and spout units. A vertical post |90 (Fig. 20) is xedly secured to and depends from the bar |8a which is xedly connected to the side members of the upper units a, and slidably extends through a channelled portion |9| in the bar ||8a which is connected to the units a of the lower series. A post |92 has its upper end xed to the outer member 10 of the upper series of units a, and is slidably guided in a block |95 which is fixed to the outer member 10 of the lower series of units. These posts connect the group e of the upper and lower series of units for conjoint transverse movement and permit vertical adjustment of the upper series relatively tothe lower series. A screw shaft 200, which is provided with a crank 203, is journalled and confined against longitudinal movement in a bearing 20| formed on one of the side frames 30 and is screw-threaded to a block 202 which is fixed to the longitudinal bar |89, which connects the bars H8a and |0| of the lower series of units for transverse movement. Rotation of crank 203 will rotate screw shaft 200 to shift transversely bar |89 which is connected to the bars I|8a and bar |8| of the lower series of compressor and spout units. The posts |90, |92 will be simultaneously shifted and impart like movement to the group a of the upper units of said series. The transverse shifting of groups a. will simultaneously operate the linkages for shifting the intermediate units c.

The mechanism for driving the conveyor chains comprises an electric motor 220, a counter-shaft 22| journalled in the side frames 30, a pulley 222 on shaft 22| driven by a belt 223 from a pulley 224 on the motor shaft; a stud shaft 225 journalled in one of the side frames 30; a sprocket wheel 226 on shaft 22| which drives a chain 221; a sprocket wheel 228 on shaft 225 driven by chain 221 a sprocket wheel 228 on shaft 225 which drives a chain 23| and a sprocket wheel 232 on the shaft H4 which carries the sprockets 64 for driving the conveyor chains of all the lower units. The drive shaft 35 of the delivery section is driven from shaft H4 by a sprocket 50a on one end of shaft H4 (Fig. 9), a chain 5|, and a sprocket 52 on the shaft 35. The shaft H5 which carries all of the sprockets 64 for driving the conveyor chains 60 of all of the upper units, has secured thereto a sprocket wheel 234. A stud shaft 238 is supported by a pair of links 239, 239m which are pivoted co-axially with the shaft H5 and the shaft 35, respectively. `Sprocket wheels 236, 230 are j ournalled on stud shaft 239. A chain 24| extends around a sprocket 233 which is on, and driven by the shaft 35, and around sprocket 240 on the stud shaft 238. A sprocket 236 fixed to the sprocket 230 drives the sprocket 234 on the shaft I5 from the sprocket 236. The chain 24| passes under an idler sprocket 244 on the shaft H4. rihis driving connection between the shaft 35 and the shaft H5 for the upper series of compressor and spout units permits vertical adjustment of said units while maintaining the driving connection.

The transverse spacing of the unite for conveying loose filling-material to the compressor section, each of which comprises the group of three conveyor chains 31, the sprocket wheel 38 on the shaft 35, and the idler sprocket 39 on the shaft 39, which is adjustable along said shaft to accommodate the filling of casings of different widths. The sprockets 31 have sliding engagement with shaft 35, like the idler sprockets 39 are slidably adjustable along the shaft 36. The unit at one side of the machine is xedly secured against transverse movement.

A linkage is provided adjacent each end of the channel bars 49 for simultaneously and transversely adjusting the units of the delivery section relatively to the unit fixed against transverse movement, for lling mattresses of different widths. Each of these linkages (Fig. 6) comprises a link 258 pivoted at 259 to the block i3 of the transversely fixed unit; a link 230 pivoted at 26| to the block 43 of the unit at the opposite side and pivoted at 292 to link 258; links 263 pivoted at 264 to the blocks 43 of the units adjacent the units at the side of the machine, and at 265 to links 258, 260, respectively; and links 269 pivoted at 231 to the blocks 43 of the central units, and at 258 to the links 253, 299, respectively. A transverse shaft 215 is journalled and held against transverse movement in a, bearing 216 (Fig. 4) fixed to beam 34 at one side of the machine, and is provided with a screw thread 211 for engagement with a screw collar 218 which is fixed to one of the side plates 42 of the unit at the opposite side of the machine. A similar screw shaft 219 is provided at the rear end of the machine. Sprocket wheels 282, 283 are fixed to the screw shafts 215, 219, respectively, and connected by an endless chain 284. vShaft 215 is provided with a polygonal end 296, to which a crank may be applied for rotating said shaft 215 for simultaneously rotating through the sprocket wheels 282 and 283 and chain 284, the screw shaftl 219.

A characteristic of providing conveyor units,A

which include a group of chains on a single guidebar which individually guidesfthe chains,

is that the chains may be closely spaced togetherfor more eciently engaging the filling-material and conveying it forwardly. By providing con- Y veyor chains, whichextend continuously along the convergent and horizontal portions ofthe units of the compressor and spout sections,ithe-- ow of yilling-material is uninterrupted, and the v -1 construction is greatly simplified By-including a group of cha-ins in each unit, and providinga single guide bar withtracks-for the group of` f chains, the construction isA smplied. p

The sliding connection at the inner end of bars SG and spacer sleeves 14 on the side members 1B, and the slidability of shoes 90 on their supports, which carries the screws HS, will permit the springs to shift the guide bars to tighten the chains E@ as soon as the screws H9 are loosened. The screws H9 are then tightened to lock the shoes 99 to the slidable blocks in the supporting bars, so that the guide bars Si? will be fixedly positioned to keep the chains taut. This expedites the tightening of the chains when it becomes necessary.

The transverse adjustment of the compressor and spout units may be effected while the upper compressor and spout sections are adjusted for different thicknesses in mattresses, and said upper sections may be adjusted vertically without distributing the transverse spacing of the units.

The invention exemplifies a machine for flllin mattresses, cushions, and the like, which comprises units, each of which includes a group of parallel chains and a guide bar with tracks thereon, which makes it possible to provide chains in close relation for eiciently advancing the filling-material. The invention also provides a machine in which the units, including a group of endless conveyor chains, extend continuously between the compressor and spout sections. The invention also comprises simplified means for adjusting the spacing between the conveyor units. The invention also exemplifies improved means for keeping the endless conveyor chains taut. The invention also exemplifies a detachable sectional side closure for the units which is demountable and adapted to be placed on any of the units. The invention also exemplifies improved means for stripping the lling-material from the conveyor chains, at the end of which the material is discharged into the casing.
